This mod makes rabbits (hares) breed more quickly, grow faster, and have larger litters. They're also slightly more taming friendly. That's it.
As far as testing goes, it's not done any Save Game mangling for the few folks I know that play.

License: Go for it, do absolutely anything with it - it's just a copy of Core Hares slightly adjusted.
Nothing like a colony guarded by rabbits.
300 of them
Ha! Next mod (more of an actual mod than this): "Night of the Lepus".
Breed the rabbits enough and they get huge and violent. ;D
